The attorney took them to his office at 101 North J Street in Lake Worth, then called the Palm Beach County Sheriff's Office to have officials pick them up.

PBSO deputies responded at about 10 a.m. and immediately evacuated the building, according to a release issued by that office. The grenades were safely removed.

"The best thing you can do when someone finds something like this is to obviously not to move it," Palm Beach County Sheriff's Office spokesman Lt. Alan May said. "Just evacuate what ever you have and (call) the sheriff's office in the area, and let them make a decision of what's going to happen with the items."
